Help choosing driver

hello, I need help choosing correct driver. Would like to run 2 cxm 32's. Would a hlg240 be ok? obviously 1 cxm 32 max is 240 watts. Better to run them at say 50%, correct.

IF I want to run 4 cxm 32, Should go with 1 hlg 480 or 2 hlg240?

I would run pairs on a HLG-320H-C2800.

It's hard to find heatsinks for 120w cobs unless you go for active heatsinks. Most people would run cobs at 60w each or below.
The hlg qb96 is a good cob replacement, its price is very competitive if you count in the heat sink
